The brooch/pin is marked 925 along with hallmarks. The last photo shows them clearly. It has been gently acid tested to confirm purity. The total weight of sterling and stone is 12.21 grams.
Ring boxes and other display pieces are not included. The items I list are pre-owned. Some are vintage or antique.
They may not be perfect but I will describe to the best of my ability. My sterling silver jewelry and items are pre-owned and pre-loved. Older quality silver offers a soft patina that is warm and unique to the history of each individual piece. There may be light surface scratches but that is normal for silver.I do my best to describe the items. However, I occasionally miss something. Negative/neutral feedback neither helps nor resolves problems. It is permanent and damages the reputation that we strive so hard to establish.
